Carol's computer monitor died, and she bought a new one. Now she has a screen that says "Welcome to your new computer" and her settings have vanished. After running a restore point, she got it back to normal, and the same thing happened the next day. Leo says that the her Windows profile may have gotten corrupted, which can happen. Carol can find instructions on how to fix a corrupted profile at support.microsoft.com. The best way to fix it is to reinstall Windows, though.
It should go without saying that having a current backup of your computer is an essential preventative measure in case the worst happens. But there's another very simple step you can take that can potentially save you a lot of headache -- create a secondary administrator account. Make sure that account is pure and is in the default Mac or Windows configuration.
David has a problem where his computer shuts off after awhile and he has to log in twice to get it back. Leo says he's had a similar issue with a MacBook. As long as he uses it every day, it's not problem. But after a few days, this issue would pop up. Leo just logs out and shuts down and that solves the issue. David should uncheck put the hard disk to sleep. He should also disable Power Nap. Those things may prevent this from happening. Turning off the Sleep function entirely will work as well, but he'll be using power then.
Paul can't get his resume off his computer because he can't log onto it. He gets a user profile loading error. Leo says that the good news is that the data is probably not gone. It's always helpful to have the admin account as an unused account, and to only run as a standard user. Then he could always go into the Admin account and have access to all files.
